PREFERABLE MODE OF CARRYING OUT THE INVENTION Example 1

See FIG. 1, In example 1, the motorized/manual clutch of curtain track1, set on a curtain track 2, the track is installed belt 4 which isdriven by motor 3 and carrier hook parts 5 which are used to hangcurtain. As shown in FIG. 1, reference numeral 6 represents a drive box,and reference numeral 6 represents an end box 7.

Refer to FIG. 1 again, in example 1, the motorized/manual clutch 1 iscomposed of a clutch body module 11 and a clutch bar module 12, the twoparts are separation and reunion. There is a gap 41 in the belt 4, theclutch body module 11 is set in the gap, connected with the driven beltand moved with the belt. The clutch bar module 12 is set under the bodymodule 11 and connected with carrier hook parts 5, drive the carrierhook move.

See FIG. 2, In example 1, the mentioned clutch body module 11 iscomposed of a clutch body 111 and two connectors 112, there is a hole1111 in the middle of the clutch body 111, the two connectors 112 areconnect with clutch adapters and belt 4 which are at the both sides ofthe hole by fixer 113.

Refer to FIG. 2 again, In example 1, the mentioned clutch bar module 12is composed of connector 121, clutch bar 122, sewing bar 123 and carriergroup 124. The connector is hung on the track 2 by the carrier groupwhich is installed on itself, and connected with curtain carrier hookmodule. There is a hole 1211 on the connector 121 which is adapted withthe hole 1111 on the clutch body, and also a slot 1212 for sewing bar.There is enough space 1213 for end part of the sewing bar inside thementioned slot on the connector. Insert the upper part of clutch bar 122into the hole 1211 on the connector 121 and up to the hole 1111 on theclutch body 111, set one end of the sewing bar 123 in the slot 1212 ofthe connector in crosswise and revolvable connected with the connector121, there is a slot for sewing bar in the lower part of the clutch bar122, insert middle part of the sewing bar into the slot, make it andlower part of the clutch bar 122 revolvable connected to drive theclutch bar move up and down.

FIG. 1 and FIG. 2 show the motorized state of this new curtain track inexample 1. At this moment, the clutch bar 122 of the clutch bar module12 is in the hole 1111 on the clutch body 111, the clutch body module 11is connected with the clutch bar module 12. Turn on power and pressswitch, the motor 3 will revolve and drive the belt 4 move in the doubletrack, and the clutch 1 which carries curtain will move with the belt,so the track system will be operated.

See FIG. 3, it is the separate state of the swing bar on themotorized/manual clutch in example 1. At this moment, the clutch bar 122of the clutch bar module 12 is out of the hole 1111 on the clutch body111, the clutch body module 11 and clutch bar module 12 aredisconnected. It can be manual operated. When power cut or any problemof motor, pull down the swing bar 123 by hand, separate the clutch bar122 and the clutch body 111, the curtain can be open and close at anyposition by hand from any position.

See FIGS. 4 & 5, they show a separate state of the motorized/manualclutch in manual operation state in example 1. At this moment, theclutch bar 122 of the clutch bar module 12 is out of the hole 1111 onthe clutch body 111, the clutch body module 11 and clutch bar module 12are disconnected. Now just pull the swing bar 123 horizontally tooperate the curtain open and close. In FIG. 4, the clutch body module 11and the clutch bar module 12 are in different position. In FIG. 5, thebelt 4 is above the clutch bar module 12, but not the clutch body module11.

Example 2

FIG. 6 and FIG. 9, example 2, show the motorized state and manual stateof the motorized/manual clutch of curtain track. They are correspondingto FIG. 1 to FIG. 3 and FIG. 5.

The following are the different structure of the motorized/manual clutchin example 2 from example 1.

Refer to FIG. 7, it show the difference of motorized/manual clutchstructure between example 1 and example 2:

(1) There is a carrier bearing 126 on the upper part of clutch bar 122.make the upper part of clutch bar 122 through the hole 1211 on theconnector 121 more smoothly and up to the hole 1111 on the clutch body111

(2) There is a spring 125 in the middle part of the clutch bar 122,refer FIG. 7, the spring 125 is at the connecting part of carrierbearing 126, clutch bar 122 and sewing bar 123. In common, if the sewingbar 123 can sustain weight of curtain, it can always keep level with theforce of the spring 125.

(3) There is a hole 1231 which extend alongside the clutch bar operationdirection in the middle part of the sewing bar 123, the lower part ofclutch bar 122 move round or up and down in the hole 1231, ensure enoughspace for the clutch bar 122 to work up and down.

When the belt 4 moving, the connector 121 touch the carrier bearing 126on the upper part of the clutch bar 122, make the carrier bearing 126insert the hole 1111 on the clutch body 111 gradually under the force ofthe spring 125. At this moment, the sewing bar finish the connection ofthe clutch body module 11 and the clutch bar module 12 in its horizontallevel condition. To separate the clutch body module 11 and the clutchbar module 12, pull down the sewing bar 123, which will make the carrierbearing 126 on the clutch bar 122 out of the hole 1111. Under the forceof spring 125, the carrier bearing 126 on the upper part of clutch bar122 is withstand the double track all the time.
